BALING-PRESS PACKER.

Application filed December 2, 1912.

Specification of Letters Patent.

Patented Sept. 2, 1911,

Serial No. 734,594.

To all whom it may concern Be it known that I, LEWIS B. l/Vroan'r, a citizen of the United States, residing at Vincennes, in the county of Knox and State of Indiana, have invented a new and useful Billing-Press Packer, of which the following is a specitiaition, reference being had to the accompanying drawings and to the letters and figures of reference marked r 5 tivc view of the more essential features of 1 the invention; Fig. 4t, a perspective view of one Of the parts of the improvement; Fig. 5, a fragn'ientary vertical section approxiinately on the a fragmentary section approximately on the 1 line .13 ll in Fig. 5; Fig. 7, a side elevation thereon.

This invention relates to mechanism of the type that is designed for assisting in feeding hay or other substance into baling presses and for packing the substance in the baling chamber thereof preparatory to compressing the substance into the form of bales, the invention having reference more particularly to a packer that is adapted to yield without liability to become fractured when the accumulation of hay or other sub stance in the baling chamber increases the resistance and prevents the packer head from traveling its maximum extent.

The object of the invention is to provide an improved and ellicient packer or feeder for baling presses that shall be so constructed as to permit a maximum travel of the packer head and also variable extent of travel downward as the baling chamber becomes filled, and exert practically equal pressure at all strokes, and which shall be adapted to be applied to various forms of presses.

A particular object of the invention is to provide an improved packer of the above mentioned character that shall be especially adapted to be applied to the baling press forming the subject-matter of my pending application for Letters Patent of the United States, Serial No. 664,250, filed December 6, 1911.

With the above mentioned and other objects in view, the invention consists in an improved packer arm provided with a spring for affording a limited extent of yield, and provided also with a slip-connection permitting the actuating mechanism 'of the arm to travel a uniform extent while permitting variable extent of travel of the packer head when in action, to the end that the packing force shall be practically constant during the filling of the baling chainher; and the invention consists further in the novel parts and in the combinations and arrangements of parts as hereinafter particularly described and further defined in i the accompanying claims.

'lhri'nighout the drawings similar reference characters indicate corresponding elements or features of construction herein re- 'terred to.

In order that the invention and its mode of operation may be clearly understood it is illustrated in connection with parts of the baling press above referred to which coniprises two suitable sides 1 and 2, a bottom 3 secured to the sides, a top plate a secured on one end portion of the sides, a top plate 5 secured to the opposite or rearward end portion of the sides, an upwardly yielding plate, (3 hinged to the plate 5 with space left between the plates 4 and G into which to feed the hay or other substance to be baled in the baling chamber formed in the press frame. A. raininer 7 is suitably guided in the baling chamber for pressing the sub stance into compact bales. Two gear wheels 8 and 9 provided each with an axial shaft 10 are mounted in the two sides respectively and connected together by a crank pin 11, a pitinan 19 being connected to the crank pin and also to the rainmer.

In practically carrying out the objects of the invention two bearing blocks 13 and 1st are secured upon the sides of the press frame and are adapted to constitute journal bearings having caps 15 and 16 thereon respectively and rotatably supporting a driving shaft 17 having two pinions l8 and 19 secured thereto that are in mesh with the two gear wheels 8 and 9 respectively, a gear wheel 20 being secured to the shaft to be suitably driven. The blocks 13 and 141- are adapted to also form two other journal bearings 21 and 22 respectively on the rearward side thereof which are provided respectively with caps 23 and 24, the caps having integral standards 25 and 26 thereon respectively. A rock shaft 27 is rotatively mountedin the journal bearings 21 and 22 and has a. rocker arm 28 secured thereto that has a longitudinal slot 29 therein. A crank arm 30 is secured to an axial shaft 10 and has a crank pin 31 thereon that extends into the slot and preferably has a roller 32 thereon. The rocker arm 28 and the crank arm 30 are suitably set so as to be in harmony with the movement of the rammer 7. The shaft 27 preferably is provided with two collars 33 and 34; toprevent longitudinal movement of the shaft relative to its supporting boxes. T he standards 25 and 26 support a pivot rod 35 at a suitable distance above the shaft 27.

The packer arm, which assists in feeding the substance into the baling chamber, comprises a novel rocker arm 36 which is fixedly secured at one end to the rock shaft 27 and its opposite end has a cam-face 37 thereon that is curved and eccentric to the axis of the rock shaft, the end of the rocker arm having also a concave depression 38 at the lower end of the cam-face. Two reach-arms 39 and 40 are pivotally connected at one end to the shaft 27 at opposite sides of the rocker arm 36. A feed head 41 of suitable construction has a downwardly extending packing arm 12 and is provided with two pivots a3 and 4- 1, one of which is below the other and connects the reach arms with the head, two rods 415 and 4L6 being connected to the upper one of the pivots and also to the pivot rod 35. A pivot 17 is connected to the reach arms 39 and 10 at a suitable distance from the shaft 27 and a connecting rod 18 is connected at one end thereto and has an oblique angled portion 19 that normally is approximately on or below the plane of the under side of the reacharms, the portion 49 extending toward the rocker arm 36, and it has a bolt hole 50 therein, the portion 19 having also a cylindrically shaped end 51 that is normally seated in the depression 38 and may slide in contact with the cam-face 37 when forced out of the depression to constitute the slip connection between the rock shaft and the feeder head, the end 51 preferably having guide flanges 52 and 53 on opposite ends thereof that operate at the opposite sides of the rocker arm. A cross bar 5 1 is seated upon the reach arms 39 and 10. A bolt 55 extends loosely through the bolt hole 50 in the rod or bar portion 19 and has a head 56 seated against the under side of the said portion, and having a coil spring 57 on the cross bar and extending about the bolt, and a washer is seated upon the spring and is retained on'the bolt adjustably by means of a nut 59 screwed on the bolt, so that the tension of the spring may be varied.

It is obvious that a platform, unnecessary to describe in detail, is commonly arranged upon the press frame upon which to place the loose hay or other substance to be fed into the baling chamber.

In practical use, when the machine is in operation and an attendant feeds the hay or other substance into the baling chamber, while the rammer 7 is retracted the feeder arm 42 is thrust down into the baling chamber to pack the hay or substance therein upon the floor 3, and when the packer arm is descending or when rising it appears as more clearly shown in Fig. 5 but when the hay or substance accumulates the travel of the packer head All downward is resisted and limited by the accumulation, while the rocker .arm 36 continues through its full stroke, with a tendency to swing away on its axis from the axis of the pivot 47 on which the rod or bar 4:8 swings away from the shaft 27, so that the end 51 slides out of V the depression 38 onto the cam-face 37, which being eccentric remains in contact with the end 51 and maintains the required pressure on the spring 57 to enable the packer head to exert the desired pressure on the hay to pack and to assist in feeding it to the baling chamber, the position of the slip connection relatively being shown by broken lines in Fig. 5 and in full lines in Fig. 3. When the rocker-arm 36 swings upward the end 51 drops back into the depression 38 and thereby enables the rocker-arm to elevate the reach-arms 39 and 40. Other results of the operation of the invention will be readily understood from the foregoing description of the details of construction and the function of the several parts of the improvement.

Having thus described the invention, what is claimed as new is 1. A packer including a rock-shaft, a rocker-arm fixed on'the rock-shaft. and having a cam-face On its end that is eccentric to the rock-shaft, a reach-arm pivoted to the rock-shaft, and a friction tension device movably mounted on the reach-arm in movable contact with and spring-pressed to the cam-face.
